fix(fleet): repin rewrites stale dryrun refs, not just rc refs (#392)

The repin's in-repo ref rewrite only matched vX.Y.Z-rc.N, so a hand-written setup-cli pin left pointing at a vX.Y.Z-dryrun.N tag (from a dry-run validation repin) was never updated to the current rc. After the dryrun tags were pruned, primary and rollback-dispatch failed at Set up job (Unable to resolve action stablekernel/cascade@v0.6.0-dryrun.2) and the first live nightly fleet went red. Broaden the grep and sed to match -(rc|dryrun). so any stale prerelease pin self-heals to the rc on the next repin. Part of #373.
